还在为每天数万条告警头疼？看我如何用LLM让运维效率提升10倍

近来留意到诸多技术团队着手探寻大模型于实际业务里的落地情形，特别是在运维这个看似传统、实则急需效率突破的范畴，AI的介入正默默改变着工程师们处理系统告警的日常。身为长期关注AI应用落场的观察者，我觉得这种把LLM与AIOps相结合的尝试，意味着运维工作正从“人工排查”迈向“智能协同”的新阶段。
告警洪流困境
当下，大型互联网平台每日所产生的告警数量，已然突破十万量级。有某头部电商平台的运维负责人透露，在2024年促销季那段时期，其监控系统在单日捕获的告警事件数量达到了27万条，如此这般，致使传统人工筛选模式难以进行应对。
告警内容当中，既有结构化数据，又涉及大量非结构化文本。系统日志、业务指标、用户反馈等多源信息，需要运维工程师同时处理，而这种多模态数据混合的场景，进一步加大了分析的难度。
关联分析瓶颈
架构呈分布式时，单个故障会有可能触发数十个存在关联的告警。2023年，有一份某金融科技公司所做的事后分析报告表明，因为没能及时识别出数据库慢查询跟支付超时二者之间的关联，所以致使业务中断，这种中断持续了47分钟。
基于传统规则的关联分析方法，需预先去定义故障模式，新型微服务架构展现出的动态特性，致使规则维护成本急剧增加，这造成将近三成的复杂故障，因其无法借助既定规则及时发出预警 。
LLM语义解析
规模较大的语言模型于领会告警文本层面呈现出别具一格的优势。某家云服务商在2024年年初所开展的测试显示，经过专门设定训练的LLM能够确切辨认93%的告警语义，其中涵盖了针对模糊表述的关键信息提取。
模型借助对告警上下文予以分析，能够自行补足缺失的场景资讯。比如说处于出现“接口超时”告警这种状况时，系统会同步去调取相关服务的部署变更记载，进而形成完备的分析链路。

以LLM为基础构建的告警分级系统，于众多个互联网公司当中获得了验证。某社交平台施行智能分级之后，高优先级告警识别具备的准确率，自百分之六十八提升到了百分之八十九，切实减小了重要告警被淹没的可能性。
此系统借助实地剖析告警内容、波及范围以及过往数据，灵活变动优先级评分来实行动态调整。运维团队能够依据评分结果恰当地分配处理资源，以此防止过度留意那些并非关键的告警发生 。
实战效能验证
于近期某视频平台开展容量扩容之际，LLM辅助系统于3分钟之内识别出存储集群异常同CDN节点故障之间的关联性，传统方法则平均需25分钟方可构建此种跨系统关联 。

此平台的运维总监讲道，智能分析系统把平均故障定位时间，缩减到了原本的四分之一。尤其是在应对跨地域部署的业务出现异常的状况时，系统呈现出比人工远远高出的分析效率。
实施路径建议
开展技术团队所建议的采用渐进式实施方案，首先要在测试环境构建能够作为告警依据事物的样本库，接着运用三至六个月的时长去完善模型对于相关事物的理解能力，之后再一步步地将其推广至生产环境 。
起始阶段的时候，应当去构建用人担任角色来再次核查核实的机制，如此这般才能够保障模型做出的输出结果具备可靠的性质。有一个从事制造行业的数字化团队，采用了双轨同时运行的模式，在连贯不间断的30天时间里，都没有出现差错的情况进行分析之后，才把LLM分析得出的结果归入到决策的流程里面。
在实际工作里，各位技术同仁有没有碰到过让你记忆深刻的告警分析实例呢？欢迎于评论区把你的实战经历分享出来，同时也期望知晓更众多行业在智能运维这方面的创新实践情况。要是感觉本文对你有启发作用，那就请点赞给予支持且分享给更多有需求的伙伴 。
